Axel Swap

[AaronRich]

Can anyone on here tell me if I can put a dually rear end from a 2003 chevy under my 2012 3/4 ton? I'm wanting to do the swap but im not sire if it will work for sure or not and before I waste money and a trip to get the rear end I'd like some input. it is the same gear ratio so I know I wouldn't have to worry about that. I'm thinking my only other main difference might be where the drive shaft bolts up but I should be able to swap that over from my axle right? I guess I'm mainly asking if anyone has done anything like this to know if the mounting points are the same and if the park brake cables will work etc. any input is appreciated thanks for reading and I apologize if this is on another post already that I missed.

No. Track width, U joints, where the springs line up, u bolts, parking brake system, hub size and bolt pattern, its all different. If you think you need a dually, buy a dually.
